Definitions
- the invention relates to a filter plate for a particle filter for separating particles from an exhaust gas flow of an internal combustion engine according to the closer defined in the preamble of claim 1.
- the invention further relates to a particulate filter for the separation of particles from an exhaust stream of an internal combustion engine.
- a filter for separating impurities from exhaust gases comprising a filter body with a plurality of sintered metal powder filter plates, which are arranged so that they form a plurality of adjacent flow channels.
- the individual filter plates are wave-shaped and are flowed through in the longitudinal direction. This waveform of the filter plates leads to each delimited longitudinal channels that clog very quickly with ash and thus can affect the effect of the filter. Furthermore, results from the so pronounced channels a very highly directed flow, which prevents distribution over the plane of the filter plates and thus leads to an increased exhaust back pressure.
- Another disadvantage of the known filter plates lies in their low rigidity, which makes the handling of the same sometimes considerably more difficult and may affect their durability.
- Another particle filter is described in WO 02/102494 A1.
- a plurality of filter pockets are arranged in a star shape around the circumference of a central bore, which have a triangular cross section and in which a spacer element is used, which is intended to prevent deformation of the filter pockets by the exhaust gas pressure.
- this also referred to as "spacer" spacer element is an additional component, which represents an additional expense in the production of the particulate filter.
- the filter plates have respective characteristics which are intended to bring about a support of the filter plates relative to one another.
- the filter plates are usually installed with a specific bias as a filter body in a filter housing and the filter plates are additionally compressed by the weight and by the exhaust pressure in the case of most given installation position, the space located between the filter plates can be very easily reduced and even completely eliminated, so that there is a significant impediment to the flow. This can not be reliably prevented even with the solution according to DE 101 28 938 A1.
- the spacer element of the filter plate of the invention has an inner elevation or depression extending away from the surface area and an outer depression or elevation surrounding the inner elevation or depression extending in the opposite direction of the inner elevation or depression away from the surface area.
- a spacer element is understood to mean a defined subregion of a respective filter plate, which due to its structure causes the maintenance of a spacing of adjacent filter plate.
- a particle filter for separating particles from an exhaust gas stream of an internal combustion engine with a plurality of filter plates arranged side by side is specified in claim 6.
- Such a particle filter makes use of all the advantages of the filter plate according to the invention, so that a flowability of the inlet and outlet channels is always ensured.
- the spacer elements are arranged on the filter plates, that the spacer elements of adjacent filter plates contact each other, and that the filter plates have such an arrangement to each other, that in each case an inner elevation of a filter plate on the inner recess of the adjacent filter plate or an outer recess of a filter plate on the outer elevation of the adjacent filter plate comes to rest.
- Fig. 1 is a plan view of a filter plate according to the invention.
- Fig. 1 shows a filter plate 1, which is used to form a particle filter, not shown in its entirety, for the separation of particles from an exhaust stream of an internal combustion engine.
- the location of use which is preferably located within an exhaust system of the internal combustion engine, and the operation of such a particulate filter is described in principle in DE 42 34 930 Al, which is why will not be discussed in more detail below.
- the filter plate 1 consists essentially of a sintered metal powder coated, gas-permeable carrier material and has a substantially in one plane, namely in the present case in the image plane, extending surface area 2.
- a plurality of spacer elements 3 are provided on the surface area 2 a plurality of spacer elements 3, whose structure will be explained below with reference to FIG. 2. Any number of spacer elements 3 can be arranged over the area region 2 of the filter plates 1, and it is also possible to combine these spacer elements 3 with further spacer elements not described in detail herein. 2, a part of a filter body 4 is shown, which is formed by a parallel juxtaposition or stacking of individual filter plates 1 and 1 'and forms the particle filter together with other known and therefore not shown components.
- the spacer element 3 extends from the surface area 2 upwardly away, inner elevation 9 and the inner elevation 9 surrounding, down, ie in the opposite direction of the inner elevation 9 away from the surface area 2 outer recess 10th having.
- the outer recess 10 surrounds the inner elevation 9 on its entire circumference and is substantially annular, whereas the inner elevation 9 is formed substantially circular.
- the outer recess 10 surrounds the inner elevation 9 only partially.
- other forms of inner elevation 9 and the outer recess 10 are conceivable.
- the outer recess 10 adjoins directly to the inner elevation 9, so that, starting from the inner elevation 9, the mean level of the surface area 2 is only reached again outside the outer recess 10.
- the arranged below the upper filter plate 1 filter plate 1 ' has a mirror image of the spacer element 3 of the filter plate 1 formed spacer element 3'.
- the spacer element 3 'thus has an inner depression 9' extending downwards away from the surface region 2 'and an inner depression 9' which extends upwards, ie in the opposite direction of the inner depression 9 'away from the surface region 2' outer elevation 10 'up.
- the outer elevation 10 ' surrounds the inner recess 9 1 on its entire circumference and immediately adjoins the same. Furthermore, the inner recess 9 'is substantially circular and the outer elevation 10' is formed substantially annular.
- the spacer elements 3 and 3' on the filter plates 1 and 1 arranged so that the spacers 3 and 3 1 of adjacent filter plates 1 and 1 'contact each other.
